FYI - we finally identified the issue in OUR case - and we have 2 bugs
CSCun65437, CSCvc99660 and we finally got a fixed version of the firmware.... If you have this issue review these bugs and ask your TAC CSE to view them as well - if it's relativ...
sorry - you have to get it from TAC I can't provide it directly....
You can reference my customers SR 639226317 if you'd like but they have to publish the ES for you...
Good Luck!!
